This answer to the Space SE question What do these patterns on Virgin Galactic's VSS Unity represent, and how are they applied? indicates that one of the aerospacecraft representations on the Unity is the Bell X-1, and comments there suggest that the shape of the wing might not be completely accurate.
It may be possible that the shape evolved during development, but I'd like to ask; What is the shape of the Bell X-1 wing, and is the representation of it in the artwork on Virgin Galactic's VSS Unity correct?
